4.2 Sambungan Pendawaian
Refer to the wiring diagram on the side of the unit and the instructions below for correct connections. Use appropriate gauge wires for all connections.

Figure 4.2: Detailed wiring diagram on the side of the MC701 unit, showing connections for power, sensor input, SSR, and relay outputs.
- Power Supply (85-265VAC): Connect to terminals 8 and 9.
- SSR Output (OUT): Connect to terminals 10 (+) and 11 (-).
- Relay Output (RELAY): Connect to terminals 13 (NO - Normally Open) and 14 (NC - Normally Closed). Terminal 12 is the common (COM).
- RTD Input (PT100): Connect to terminals 4 (A), 5 (B), and 6 (B).
- Thermocouple Input (TC): Connect to terminals 5 (+) and 6 (-).
- Alarm Outputs (AL1, AL2): Connect to terminals 1, 2, and 3.
5. Arahan Operasi
5.1 Paparan Terlaluview
The MC701 features a dual display:
- PV (Process Value): Displays the current measured temperature.
- SV (Set Value): Displays the desired target temperature.
Lampu penunjuk:
- OUT: Indicates output status (heating/cooling).
- AT: Auto-tuning indicator.
- ALM1, ALM2: Alarm indicators.
5.2 Fungsi Butang
- SET: Enters parameter setting mode or confirms a setting.
- < (R/S): Shifts cursor during setting, or resets alarm.
- V (Down Arrow): Decreases value during setting.
- ^ (Up Arrow): Increases value during setting.
5.3 Menetapkan Suhu Sasaran (SV)
- Tekan ke SET butang sekali. Paparan SV akan mula berkelip.
- Gunakan ^ dan V butang untuk melaraskan suhu yang dikehendaki.
- Gunakan < button to shift the cursor for faster adjustment.
- Tekan SET sekali lagi untuk mengesahkan SV baharu dan keluar dari mod tetapan.
5.4 Tetapan Parameter Lanjutan
To access advanced parameters (e.g., PID parameters, alarm settings, input type, temperature unit), press and hold the SET button for several seconds until the first parameter code appears on the PV display.
- guna ^ dan V to navigate through parameters.
- Tekan SET kepada view or edit a parameter's value.
- Laraskan nilai menggunakan ^, V, dan <.
- Tekan SET to save the value and return to the parameter list.
- To exit advanced settings, press and hold SET again, or wait for a timeout.
6. Penyelenggaraan
Regular maintenance ensures the longevity and optimal performance of your MC701 controller.
- Cleaning: Wipe the display and casing dengan kain lembut dan kering. Jangan gunakan pembersih atau pelarut yang melelas.
- Ventilation: Ensure the ventilation slots on the sides of the unit are not obstructed to prevent overheating.
- Connections: Periodically check all wiring connections for tightness and signs of wear or corrosion.
- Storage: If storing the unit, keep it in a dry, dust-free environment within its specified operating temperature range.
7. Penyelesaian masalah
| Masalah | Kemungkinan Punca | Penyelesaian |
|---|---|---|
| Paparan menunjukkan "HHHH" atau "LLLL" | Sensor open circuit or short circuit; temperature exceeds range. | Check sensor wiring and connection. Verify sensor type matches setting. Ensure temperature is within range. |
| Pengawal tidak memanaskan/menyejukkan | Output wiring incorrect; SV not set correctly; PID parameters need tuning. | Check output wiring (SSR/Relay). Confirm SV is set to desired temperature. Perform auto-tuning if necessary. |
| Suhu turun naik secara meluas | PID parameters not optimized; sensor placement. | Perform auto-tuning. Ensure sensor is placed correctly and securely. |
| No display/Power issue | Tiada bekalan kuasa; pendawaian yang tidak betul. | Check power connections (terminals 8 & 9). Verify power source is active. |
